A convenient method for the total synthesis of all the stereoisomers of febrifugine and halofuginone using D-arabinose and L-arabinose as the key starting materials is reported. Apart from the inherent stereocenters in these pentose sugars, the method utilizes the selective hydrogenolysis of the anomeric O-benzyl group, stereoselective Grignard reaction and Wacker oxidation as the key steps to obtain
报道了一种以D-阿拉伯糖和L-阿拉伯糖为主要起始原料全合成非来福宁和卤夫酮的所有立体异构体的简便方法。除了这些戊糖中固有的立体中心外,该方法还利用了异头O-苄基的选择性氢解,立体选择性格氏反应和Wacker氧化作为获得总合成重要前体的关键步骤。
